A 1 000-V battery,a 3 000-W resistor,and a 0.50-mF capacitor are connected in series with a switch.The time constant for such a circuit,designated by the Greek letter,t,is defined as the time that the capacitor takes to charge to 63% of its capacity after the switch is closed.What is the current in the circuit at a time interval of t seconds after the switch has been closed?
A)0.14 A
B)0.21 A
C)0.12 A
D)0.32 A
